what are waypoints?

Q:

A: Depends on what you're talking about. The most common definition would be "supplemental navigation points along an orienteering course". If you're using a compass (land navigation) to find your way from point "a" to point "b", then your waypoints would be recognizable land formations (hilltop, stream, big ugly tree) where you stop to check your azimuth and heading. If you're driving from New York to Florida, your waypoints would be the truck stops you visit to refuel & check that you're still on the right highway. I guess we're all correct.... Here's the Wikipedia reference. A waypoint is a mapped reference travelers can easily identify on the ground and use to verify their location. Waypoints may include natural rock formations, springs, oasis, or other permanent terrain feature. A waypoint may also be considered a fixed location with a specified longitude and latitude and UTM coordinates, which is maintained by a global positioning system (GPS). Waypoints mark a destination, a point along the way to a destination, or a point of reference.
